GAS-FLASH-LIGH'I ADVERTISING DEVICE.

Specification of Letters Patent.

Patented Nov. 11, 1913.

Application filed December 1 1912. Serial No. 736,697.

To all whom it may concern Be it known that I, THOMAS JAcKsoN, subjectof the King of Great Britain and Ireland, residing at 7 Milton Courtroad, New Cross, London, S. 15., England, have invented new and usefulImprovements n and Relating to Gas-Flash-Light Advertlsing Devices, ofwhich the following is a specification.

This invention relates to improvements in gas flash light advertisingdevices of the type in which the control is effected by a multipleported device operated by a motor, and has for its object the provisionof improved means whereby a multiple system of lighting can bemechanically controlled with a great variety of efiects easily alterableand the driving effort is effected by means of the pressure of supply ofthe gas itself. I

The invention consists in the combination of a gas motor mechanismoperated by the pressure of the illuminative' gas used for flashingpurposes in one set of burners such for example as described in thespecification of United States Letters Patent 0. 1,009,313 dated 21stNovember 1911 and 1n the specification of the application for UnitedStates LettersPatent under Serial No. 719,043 and date'7th September1912 with a rotary drum device for supplying a number of separate pipesof another gas distributing system and means for controlling the supplyof the gas to each pipe w1th periodic variations so that any desiredcombination or sequence of individual lights of the second system can bedealt with in a predetermined manner.

In order that the invention may be the better understood, I will nowproceed to describe the same in relation to the accompanying drawings,reference being had to the letters and figures marked thereon.

Like letters refer to like parts in the various figures, in which Figure1 is a diagrammatic view of the devices formingthe subject matter ofthis invention, the lantern being shown on a smaller scale to that ofthe control device and motor mechanism. Fig. 2 is a front elevation ofthe multiple control valve. Fig. 3 is a sectional side elevation of thesame. Fig. 4: is an outside elevation of the r0tating member of thecontrol device. Fig. 5 is a sectional plan of one element of the con-:trol device. Fig. 6 is a developed view of the periphery of the controldevice.

I take a gas pressure supply motor appligance a such as is referred toabove for ex-' ries of pipes d connected to its wall and communicatingwith or forming ports 6 leading to the inside of the chamber Within thechamber a is disposed a rotating control device f of drum formationhaving holes which co-act with the ports 6 so as to cover and uncoverthem at the desired times. The gas is admitted to the chamber 0 from asuitable supply 9 to the interior of the rotating device f.

In order to construct the rotating control device f so as to be readilyalterable as to function I form it of a series of cylindrical parts feach having one or more spaces It to allow gas to pass from the interiorthrough the wall of each device f These parts f are adjustably mountedon a central spindle or shaft 2' and are securely fixed thereon whenadjusted by a nut 7' or in any other suitable manner. The shaft 13 iscarried on a ball bearing Z at the lower part of the chamber .0 andpasses through a gland Z at the upper part thereof. The upper part ofthe shaft z' carries a disk 70 having a series of pins Is arrangedaround it with which a detent m engages, said detent being pivoted to abell crank n rotatably mounted on a bearing a carried by the chamber 0.The other arm of the bell crank n is connected by a connecting rod 0with the movable element 0 of the motor mechanism aso that at eachoperative step of this mechanism the disk is is rotated by the detent mthrough the angle included by two adjacent pins 70 The spaces h in theparts f as illustrated in the drawing and clearly shown in Fig. 6 asdeveloped in a plane are so disposed and of such a shape as in coactionwith the ports 6 at each side of the chamber 0 will produce certainlighting effects in the lantern p which is only shown by way ofillustration of one method of carrying the invention into effect.

The lower part of the lantern p is divided into six separatecompartments 39 each of which has a transparent portion representing aletter or letters. Each compartment 10 has two burners g 9 9 beingconnected to a port 6 on one side of the chamber 0 and g to a port 6 onthe other side of. the chamber 0. The spaces h as shown in Fig. 6 aredisposed at the first, second, third and fifth division of theperiphery, each division being ig-th of the whole and the effectsproduced would be as follows :During the first increment of movement theletters would be illuminated one after the other from left to right bythe burners g and the whole would then disappear suddenly. The nextincrement of movement brings the alternate parts f in communication withthe ports 6 on the two sides of the chamber 0 respectively so that ifthe burners q emit white light and the burners g emit red light, thewords will be shown with letters of white and red alternating and wouldthen be suddenly extinguished. The next increment of movement will spellthe words in white light backward and extinguish them. The next movementwill spell the words forward in red light and extinguish them. The nextincrement of movement will give the alternate lighting of white and red,but in opposite order to the first effect and then extinguish the light.The next and last increment of movement will spell the words backward inred and extinguish them.

The upper part of the lantern 79 has a separate compartment 9 havingtranslucent portions 29 which may represent any suitable design and isprovided with burners 1" connected by a pipe 1" with the motor mechanisma. By means of the rolling ball valve arrangement 8 of the motormechanism a the flash illumination of this upper compartment isefl'ected at each operation of the machine so that the exhaust gas fromthe motor mechanism a after the motive stroke has been made is used forilluminating purposes as described in specification of the applicationfor United States Letters Patent under Serial No. 719043 and date 7thSeptember, 1912.

It is of course obvious that provision must 'be made for pilot lights tothe burners in the ordinary way but these details have been left out ofthe drawings to avoid complication.

Having thus fully described my invention I claim as new and desire tosecure by Letters Patent A rotary valve arrangement for gas flash lightapparatus comprising a circular casing, a series of ports in the wallsthereof for supplying gas to a series of burners, a series of circularelements of ring formation adapted to form a cylindrical structure, aport or ports formed in each element adapted to co-act with one of theseries of ports in said casing, a shaft adapted to rotate in said casingand means for adjustably carrying said elements upon said shaft so thatperiodic flashing of the burners can be varied at will to suit varyingcircumstances substantially as described.

In testimony whereof I have signed my name to this specification 1n thepresence of two subscribing witnesses.
